Distribution and Diversity of Gallionella-Like Neutrophilic Iron Oxidizers in a Tidal Freshwater Marsh

Microbial iron oxidation is an integral part of the iron redox cycle in wetlands. Nonetheless, relatively little is known about the composition and ecology of iron-oxidizing communities in the soils and sediments of wetlands. In this study, sediment cores were collected across a freshwater tidal marsh in order to characterize the iron-oxidizing...
